Description

Die Erfindung bezieht sich auf ein Verfahren zur Parametrierung eines Feldgerätes der Automatisierungstechnik mittels eines Bediengerätes.
Ferner bezieht sich die Erfindung auf ein Feldgerät der Automatisierungstechnik, sowie ein Bediengerät zur Parametrierung eines solchen Feldgerätes.
In der Prozessautomatisierungstechnik werden vielfach Feldgeräte eingesetzt, die zur Erfassung und/oder Beeinflussung von Prozessvariablen dienen. Beispiele für derartige Feldgeräte sind Füllstandsmessgeräte, Massedurchflussmessgeräte, Druck- und
Temperaturmessgeräte etc.. Hierbei erfassen Sensoren die entsprechenden Prozessvariablen, wie bspw. Füllstand, Durchfluss, Druck und/oder Temperatur.
Zur Beeinflussung von Prozessvariablen dienen Aktoren, z. B. Ventile oder Pumpen, über die z. B. der Durchfluss einer Flüssigkeit in einem Rohrleitungsabschnitt bzw. der Füllstand in einem Behälter geändert werden kann.
Als Feldgeräte werden im Prinzip alle Geräte bezeichnet, die prozessnah eingesetzt werden und die prozessrelevante Informationen liefern oder verarbeiten.
Eine Vielzahl solcher Feldgeräte wird von der Firma Endress + Hauser hergestellt und vertrieben.
Bekannt sind Feldgeräte, die über eine 4..20 mA Stromschnittstelle bzw. Zweidrahtleitung in eine Automatisierungsanlage eingebunden sind. Durch die Einbindung wird das Feldgerät mit Energie versorgt und kann Messwerte oder auch Stellwerte mit dem Leitsystem austauschen.
The invention relates to a method for parameterizing a field device of automation technology by means of an operating device.
Furthermore, the invention relates to a field device of automation technology, as well as an operating device for the parameterization of such a field device.
In process automation technology, field devices are often used to detect and / or influence process variables. Examples of such field devices are level gauges, mass flow meters, pressure and
Temperature measuring devices etc .. Here, sensors detect the corresponding process variables, such as level, flow, pressure and / or temperature.
To influence process variables actors, z. B. valves or pumps, on the z. B. the flow of a liquid in a pipe section or the level can be changed in a container.
In principle, field devices are all devices that are used close to the process and that provide or process process-relevant information.
A variety of such field devices is manufactured and sold by the company Endress + Hauser.
Field devices are known which are integrated into an automation system via a 4..20 mA current interface or two-wire line. As a result of the integration, the field device is supplied with energy and can exchange measured values or manipulated variables with the control system.

Neben derartigen Feldgeräten gibt es auch so genannte Vier-Draht-Feldgeräte die aufgrund ihres höheren Energiebedarfes über zwei separate EnergieversorgungsLeitungen in die Automatisierungsanlage eingebunden sind.In addition to such field devices, there are also so-called four-wire field devices which are integrated into the automation system via two separate power supply lines due to their higher energy requirements.

Dieser Zustand, also, dass das Feldgerät über die Zweidrahtleitung oder auch eine Vier-Draht-Leitung mit Energie versorgt wird, soll nachfolgend als "Online" bezeichnet werden. Im Gegensatz dazu soll der Zustand, bei dem ein Feldgerät nicht an eine Zweidrahtleitung angebunden ist und folglich auch nicht mit Energie über diese versorgt werden kann, als "Offline" bezeichnet werden. Es versteht sich von selbst, dass ein Feldgerät, weiches "Offline" ist auch keine Messwerte oder Stellwerte mit dem Leitsystem austauscht.This state, that is to say that the field device is supplied with energy via the two-wire line or even a four-wire line, will be referred to below as "online". In contrast, the state in which a field device is not connected to a two-wire line and therefore can not be supplied with energy via this, should be referred to as "offline". It goes without saying that a field device, which is "offline", does not exchange measured values or manipulated variables with the control system.

Ferner ist aus dem Stand der Technik die Europäische Patentanmeldung EP 1 862 877 A1 bekannt geworden, die sich auf ein industrielles Kontrollsystem (engl. industrial control system) und ein entsprechendes Feldgerät, welches dazu eingerichtet ist, drahtlos Sekundärsignale zu senden bzw. zu empfangen, bezieht.Furthermore, from the prior art, the European patent application EP 1 862 877 A1 The invention relates to an industrial control system and a corresponding field device, which is set up to wirelessly transmit or receive secondary signals.

Ebenfalls sind aus dem Stand der Technik die Europäische Patentanmeldung EP 1 293 853 A1 , die sich auf ein Funkmodul für ein Feldgerät bezieht und die internationale Patentanmeldung WO 2011/054618 A1 , die sich auf ein Verfahren zur Integration eines Feldgerätes in ein Funknetzwerk bezieht, bekannt geworden.Also from the prior art, the European patent application EP 1 293 853 A1 relating to a radio module for a field device and the international patent application WO 2011/054618 A1 , which relates to a method for integrating a field device into a radio network, has become known.

Ebenfalls bekannt ist, dass die Arbeitsweise eines Feldgeräts mit Hilfe von Parametern festgelegt wird, die in hierfür vorgesehene Module bzw. spezifische Speicherstellen des Feldgeräts geschrieben werden. Durch das Speichern von geeigneten Parameterwerten in den jeweiligen Modulen bzw. Speicherstellen wird die Arbeitsweise des Feldgeräts festgelegt. Dieser Vorgang wird als "Parametrieren bzw. Parametrierung" bezeichnet. Die Festlegung der Parameter wird beispielsweise vom Kunden durchgeführt. Durch die Auswahl geeigneter Parameterwerte kann der Kunde das Feldgerät an seine jeweilige Applikation anpassen. Derartige Parameter sind beispielsweise im Falle eines Füllstandsmessgerätes, welches den Füllstand eines Mediums in einem Tank messen soll, die Höhe oder auch der Durchmesser des Tankes.It is also known that the mode of operation of a field device is determined by means of parameters which are written in modules provided for this purpose or specific memory locations of the field device. By storing suitable parameter values in the respective modules or memory locations, the mode of operation of the field device is determined. This process is referred to as "Parameterization". The definition of the parameters is carried out, for example, by the customer. By selecting suitable parameter values, the customer can adapt the field device to his respective application. Such parameters are, for example, in the case of a level gauge, which is the level of a medium in a tank, the height or diameter of the tank.

Die Parametrierung derartiger Feldgeräte findet dabei heutzutage im "Online" Zustand des Feldgerätes statt. Hierzu wird zuerst das Feldgerät physikalisch an die Zweidrahtleitung angeschlossen und anschließend wird das Feldgerät mittels eines Bediengerätes parametriert.The parameterization of such field devices takes place nowadays in the "online" state of the field device. For this purpose, the field device is first physically connected to the two-wire line and then the field device is parameterized by means of an operator panel.

Dieses Vorgehen weist den Nachteil auf, dass sich ein Servicetechniker für die gesamte Parametrierung an dem für ihn möglicherweise ungünstigen Einbauort des Feldgerätes, an dem das Feldgerät zur Energieversorgung mittels der Zweidrahtleitung angebunden ist, befinden muss.This approach has the disadvantage that a service technician for the entire parameterization at the possibly unfavorable for him installation location of the field device, to which the field device is connected to the power supply by means of the two-wire line, must be.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren vorzuschlagen, dass die einfachere Parametrierung eines Feldgerätes durch einen Bediener ermöglicht.The invention has for its object to propose a method that allows easier parameterization of a field device by an operator.

Die Aufgabe wird durch das Verfahren gelöst, das in Anspruch 1 beschrieben ist. Desweitern wird ein Feldgerät beschrieben, welches zur Durchführung des Verfahrens geeignet ist.The object is achieved by the method described in claim 1. Furthermore, a field device is described, which is suitable for carrying out the method.

Die Aufgabe wird erfindungsgemäß durch ein Verfahren zum Parametrieren eines Feldgerätes der Automatisierungstechnik mittels eines Bediengerätes gelöst, wobei das Feldgerät zumindest eine Batterie, ein Funkmodul und einen nicht-flüchtigen-Speicher umfasst, wobei die Batterie das Funkmodul und den nicht-flüchtigen Speicher, in dem Parameter des Feldgerätes gespeichert werden, in einem Offline-Zustand mit Energie versorgt, wobei in dem Offline-Zustand das Feldgerät nicht an eine Zweidrahtleitung angebunden ist und nicht mit Energie über die Zweidrahtleitung versorgt wird, und wobei das Verfahren folgende Schritte aufweist:

  • Aufbau einer drahtlosen Verbindung zwischen dem Bediengerät und dem batteriebetriebenen Funkmodul des Feldgerätes, wobei das Feldgerät im Offline-Zustand betrieben wird;
  • Schreiben von Parametern in den nicht-flüchtigen Speicher des Feldgerätes, um so eine Vorparametrierung des Feldgerätes im Offline-Zustand durchzuführen;
  • Abbau der drahtlosen Verbindung zwischen dem Bediengerät und dem batteriebetriebenen Funkmodul des Feldgerätes im Offline-Zustand;
  • Anbindung des vorparametrierten Feldgerätes an die Zweidrahtleitung zur Energieversorgung des Feldgerätes;
  • Parametrierung des Feldgerätes nach dem dieses an die Zweidrahtleitung angebunden wurde, wobei zur Parametrierung zumindest auf die im nicht-flüchtigen Speicher gespeicherten Parameter zurückgegriffen wird.
The object is achieved by a method for parameterizing a field device of automation technology by means of an operating device, wherein the field device comprises at least a battery, a radio module and a non-volatile memory, wherein the battery, the radio module and the non-volatile memory, in the In the off-line state, the field device is not tied to a two-wire line and is not supplied with power via the two-wire line, and wherein the method comprises the steps of:
  • Establishing a wireless connection between the HMI device and the battery-powered radio module of the field device, wherein the field device is operated in the offline state;
  • Writing parameters in the non-volatile memory of the field device so to speak perform a pre-parameterization of the field device in the offline state;
  • Disengagement of the wireless connection between the HMI device and the battery-operated radio module of the field device in the offline state;
  • Connection of the pre-parameterized field device to the two-wire line for the power supply of the field device;
  • Parameterization of the field device after this has been connected to the two-wire line, wherein at least the parameters stored in the non-volatile memory are used for the parameterization.

Erfindungsgemäß wird die einfachere Parametrierung dadurch erreicht, dass das Feldgerät ein Funkmodul aufweist, welches bspw. gemäß dem Bluetooth-low-energy Protokoll arbeitet, wobei das Funkmodul über eine Batterie auch in dem Fall mit Energie versorgt wird, dass das Feldgerät sich im "offline" Modus befindet, also keine Energie über die Zweidrahtleitung bekommt. Hierdurch kann eine Vorparametrierung des Feldgerätes mittels Parametern die zu diesem Zeitpunkt bereits festgelegt sind bzw. feststehen, außerhalb des vorgesehenen Einbauortes des Feldgerätes stattfinden. Hierzu werden die Parameter in einen nicht-flüchtigen Speicher des Feldgerätes geschrieben, der ebenfalls mittels der Batterie im Offline Zustand mit Energie versorgt wird.According to the invention, the simpler parameterization is achieved in that the field device has a radio module, which operates, for example, according to the Bluetooth low-energy protocol, wherein the radio module is powered by a battery even in the case that the field device in the "offline "Mode is located, so no energy gets over the two-wire line. In this way, a pre-parameterization of the field device by means of parameters that are already set or fixed at this time, take place outside the intended installation location of the field device. For this purpose, the parameters are written to a non-volatile memory of the field device, which is also powered by the battery in the off-line state with energy.

Anschließend wird das vorparametrierte Feldgerät an die Zweidrahtleitung angebunden und das Feldgerät führt eine "vollständige" Parametrierung durch, in dem es auf die Parameter des nicht-flüchtigen Speichers zugreift und die Parameter entsprechend ihrer Zugehörigkeit in die vorgesehenen Module bzw. spezifischen Speicherstellen des Feldgeräts schreibt.Subsequently, the pre-parameterized field device is connected to the two-wire line and the field device performs a "complete" parameterization, in which it accesses the parameters of the non-volatile memory and writes the parameters according to their affiliation in the intended modules or specific memory locations of the field device.

Gemäß einer vorteilhaften Ausführungsform wird über einen Schalter die Energieversorgung zumindest des Funkmoduls durch die Batterie aktiviert. Auf diese Weise lässt sich die Entladedauer und somit die Standzeit der Batterie erhöhen, da das Funkmodul nicht kontinuierlich, sondern bedarfsabhängig bzw. spezifisch mit Energie versorgt wird.According to an advantageous embodiment, the power supply of at least the radio module is activated by the battery via a switch. In this way, the discharge duration and thus the service life of the battery can be increased, since the radio module is not continuously, but needs-based or specifically supplied with energy.

Gemäß einer weiteren vorteilhaften Ausführungsform wird mit einem in das Funkmodul integrierten Mikroprozessor die Übertragung der Parameter zwischen dem Funkmodul und dem nicht-flüchtigen-Speicher durchgeführt. Funkmodule mit einem integrierten Mikroprozessor erlauben eine besonders einfache Realisierung der Übertragung der Parameter zwischen dem Funkmodul und dem nicht-flüchtigen-Speicher.According to a further advantageous embodiment, the transmission of the parameters between the radio module and the non-volatile memory is performed with a microprocessor integrated in the radio module. Radio modules with an integrated microprocessor allow a particularly simple realization of the transmission of the parameters between the radio module and the non-volatile memory.

Gemäß einer alternativen vorteilhaften Ausführungsform weist das Feldgerät einen außerhalb des Funkmoduls angeordneten Mikroprozessor auf, mit dem die Übertragung der Parameter zwischen dem Funkmodul und dem nicht-flüchtigen-Speicher durchgeführt wird. Eine derartige Realisierung der Übertragung der Parameter zwischen dem Funkmodul und dem nicht-flüchtigen-Speicher bietet den Vorteil, dass der Energieverbrauch der Batterie weiter reduziert werden kann, da ein Mikroprozessor eingesetzt werden kann, der noch weniger Energie aufnimmt, als bspw. ein in das Funkmodul integrierter Mikroprozessor dies tut.According to an alternative advantageous embodiment, the field device has a microprocessor arranged outside the radio module, with which the transmission of the parameters between the radio module and the non-volatile memory is performed. Such a realization of the transmission of the parameters between the radio module and the non-volatile memory has the advantage that the energy consumption of the battery can be further reduced since a microprocessor can be used which absorbs even less energy than, for example, a Radio module integrated microprocessor does this.

Gemäß einer weiteren vorteilhaften Ausführungsform wird das Funkmodul nach der Anbindung des Feldgerätes an die Zweidrahtleitung über diese mit Energie versorgt, wobei weitere Parametrierungen des Feldgerätes mittels des Funkmoduls durchgeführt werden.According to a further advantageous embodiment, after the connection of the field device to the two-wire line, the radio module is supplied with energy via it, with further parameterizations of the field device being carried out by means of the radio module.

Gemäß einer weiteren vorteilhaften Ausführungsform wird die drahtlose Verbindung mittels des Funkmoduls gemäß dem Bluetooth-Low-Energy oder dem ANT+ oder dem WLAN Protokoll durchgeführt.According to a further advantageous embodiment, the wireless connection is performed by means of the radio module according to the Bluetooth low-energy or the ANT + or the WLAN protocol.

Gemäß einer alternativen Ausführungsform wird die drahtlose Verbindung mittels des Funkmoduls gemäß einem proprietären Funkprotokoll durchgeführt.According to an alternative embodiment, the wireless connection is performed by means of the radio module in accordance with a proprietary radio protocol.

Ferner wird ein Feldgerät der Automatisierungstechnik beschrieben, welches zur Durchführung des Verfahrens nach einem der vorherigen Ausführungsformen geeignet ist, wobei das Feldgerät zumindest ein Funkmodul, eine Batterie und einen nicht-flüchtigen Speicher aufweist, wobei die Batterie das Funkmodule und den nicht-flüchtigen Speicher mit Energie versorgt, wenn sich das Feldgerät im offline Zustand befindet. Auf diese Weise kann eine Offline-Parametrierung des Feldgerätes durchgeführt werden.Furthermore, a field device of automation technology is described, which is suitable for carrying out the method according to one of the previous embodiments, wherein the field device comprises at least one radio module, a battery and a non-volatile memory, wherein the battery, the radio module and the non-volatile memory when the field device is offline. In this way, an offline parameterization of the field device can be performed.

Die Erfindung wird anhand der nachfolgenden Zeichnungen näher erläutert. Es zeigt:

  • Fig. 1: eine schematische Darstellung einer ersten Ausgestaltung eines Feldgerätes sowie eines Bediengerätes, die zur Durchführung des erfindungsgemäßen Verfahrens geeignet sind,
  • Fig. 2: eine alternative schematische Darstellung eines Feldgerätes sowie eines Bediengerätes, die zur Durchführung des erfindungsgemäßen Verfahrens geeignet sind.
Figur 1 zeigt eine schematische Darstellung eines Feldgerätes 1 sowie eines Bediengerätes 2, die zur Durchführung des erfindungsgemäßen Verfahrens geeignet sind.The invention will be explained in more detail with reference to the following drawings. It shows:
  • Fig. 1 : a schematic representation of a first embodiment of a field device and an operator control device, which are suitable for carrying out the method according to the invention,
  • Fig. 2 : An alternative schematic representation of a field device and an operating device, which are suitable for carrying out the method according to the invention.
FIG. 1 shows a schematic representation of a field device 1 and an operating unit 2, which are suitable for carrying out the method according to the invention.

Das Feldgerät 1 umfasst hierbei eine Batterie 3, ein Funkmodul 4, bspw. ein Bluetooth Low Energy (Abkürzung: BLE) Modul und einen nicht-flüchtigen Speicher 5, in dem Parameter die dem Feldgerät 1 bei der Offline Parametrierung zugeführt werden, gespeichert sind.In this case, the field device 1 comprises a battery 3, a radio module 4, for example a Bluetooth Low Energy (abbreviated to BLE) module and a non-volatile memory 5 in which parameters supplied to the field device 1 during offline parameterization are stored.

Die Batterie 3 ist derartig in das Feldgerät 1 eingebaut, dass sie das Funkmodul 4 und den nicht-flüchtigen Speicher 5 mit Energie versorgt, auch wenn das Feldgerät 1 nicht an eine Zweidrahtleitung 7 angeschlossen ist, also sich im Offline Zustand befindet. Mittels eines Schalters 8 kann das Funkmodul 4 aktiviert bzw. deaktiviert werden. Somit lässt sich die Energieversorgung des Funkmodules 4 durch die Batterie 3 auf den Zeitraum der Offline Parametrierung beschränken. Auf diese Weise lässt sich die Entladezeit bzw. Standzeit der Batterie 3 erhöhen. Die Batterie 3 versorgt neben dem Funkmodul 4 auch den nicht-flüchtigen Speicher 5 des Feldgerätes.The battery 3 is installed in the field device 1 in such a way that it supplies the radio module 4 and the non-volatile memory 5 with energy, even if the field device 1 is not connected to a two-wire line 7, ie is in the off-line state. By means of a switch 8, the radio module 4 can be activated or deactivated. Thus, the power supply of the radio module 4 can be limited by the battery 3 to the period of offline parameterization. In this way, the discharge time or service life of the battery 3 can be increased. The battery 3 supplies not only the radio module 4 but also the non-volatile memory 5 of the field device.

Der nicht-flüchtigen Speicher 5 dient dazu, Parameter die während der Offline Parametrierung des Feldgerätes übertragen werden zu speichern, so dass die Parameter nach der Anbindung des Feldgerätes 1 an die Zweidrahtleitung 7 und der damit einhergehenden vollständigen Energieversorgung des Feldgerätes 1 zur Verfügung stehen.
Durch das Anschließen bzw. Anbinden des Feldgerätes 1 an die Zweidrahtleitung 7 werden weitere Module 12, 13 des Feldgerätes 1, wie beispielsweise ein Hauptprozessor 13 und/oder auch ein Sensor/Aktor-Modul 12 mit Energie versorgt, die im Offline Zustand des Feldgerätes 1 nicht mit Energie durch die Batterie 3 versorgt werden.
The non-volatile memory 5 is used to store parameters that are transmitted during the offline parameterization of the field device, so that the parameters are available after the connection of the field device 1 to the two-wire line 7 and the associated complete power supply of the field device 1.
By connecting or connecting the field device 1 to the two-wire line 7 further modules 12, 13 of the field device 1, such as a main processor 13 and / or a sensor / actuator module 12 are supplied with energy in the offline state of the field device. 1 can not be supplied with energy by the battery 3.

Fig. 2 zeigt eine alternative schematische Darstellung eines Feldgerätes 1 sowie eines Bediengerätes 2, die zur Durchführung des erfindungsgemäßen Verfahrens geeignet sind. Hierbei weist das Funkmodul 4 des Feldgerätes 1 keinen integrierten Mikroprozessor 9 auf, sondern einen außerhalb des Funkmoduls 4 angeordneten Mikroprozessor 10, der die Übertragung der Parameter zwischen dem Funkmodul 4 und dem nicht-flüchtigen-Speicher 5 durchführt. Fig. 2 shows an alternative schematic representation of a field device 1 and an operating device 2, which are suitable for carrying out the method according to the invention. In this case, the radio module 4 of the field device 1 has no integrated microprocessor 9, but rather a microprocessor 10 arranged outside the radio module 4, which carries out the transmission of the parameters between the radio module 4 and the non-volatile memory 5.

Ferner zeigen sowohl Fig. 1 als auch Fig. 2 ein Bediengerät 2, welches ein zu dem Funkmodul 4 des Feldgerätes 1 kompatibles Funkmodul 11 aufweist, das je nach Ausgestaltung des Funkmoduls 4 des Feldgerätes 1 nach dem Bluetooth-Low-Energy- oder dem ANT+- oder dem WLAN-Protokoll oder einem proprietären Funkprotokoll arbeitet. Ein derartiges Bediengerät kann bspw. ein Smartphone, Mobiltelefon, Laptop, Tablet-PC, PDA, Netbook, etc. darstellen.Further, both show Fig. 1 as well as Fig. 2 an operating device 2, which has a compatible with the radio module 4 of the field device 1 radio module 11, which operates depending on the configuration of the radio module 4 of the field device 1 according to the Bluetooth low-energy or ANT + - or the WLAN protocol or a proprietary radio protocol , Such a control device may, for example, a smartphone, mobile phone, laptop, tablet PC, PDA, netbook, etc. represent.

Im Folgenden wird auf das erfindungsgemäße Verfahren eingegangen. Dieses unterteilt sich im Prinzip in zwei Parametrierschritte, einen ersten Offline Parametrierschritt, in dem Teile das Feldgerät 1 ausschließlich durch die Batterie 3 mit Energie versorgt werden und einen zweiten Online Parametrierschritt, in dem das Feldgerät 1 vollständig mit Energie über die Zweidrahtleitung 7 gespeist wird und mit den Parametern, die bei der Offline Parametrierung im nicht-flüchtigen Speicher 5 hinterlegt wurden, parametriert wird.In the following, the method according to the invention will be discussed. This is subdivided in principle into two parameterization steps, a first offline parameterization step in which parts of the field device 1 are powered exclusively by the battery 3 and a second online parameterization step, in which the field device 1 is completely fed with energy via the two-wire line 7 and is parameterized with the parameters that were stored in the non-volatile memory 5 during the offline parameterization.

Die Offline Parametrierung weist dabei folgende Schritte auf:

  • Aufbau einer drahtlosen Verbindung 6 zwischen einem Bediengerät 2 und dem batteriebetriebenen Funkmodul 4 des Feldgerätes, wobei das Feldgerät 1 offline betrieben wird;
  • Lesen und/oder Schreiben der in dem nicht-flüchtigen Speicher 5 gespeicherten Parameter des Feldgerätes 1;
  • Abbau der drahtlosen Verbindung 6 zwischen dem Bediengerät 2 und dem batteriebetriebenen Funkmodul 4 des Feldgerätes 1.
The offline parameterization has the following steps:
  • Setting up a wireless connection 6 between an operating device 2 and the battery-powered radio module 4 of the field device, wherein the field device 1 is operated offline;
  • Reading and / or writing the parameters of the field device 1 stored in the non-volatile memory 5;
  • Dismantling of the wireless connection 6 between the operating device 2 and the battery-powered radio module 4 of the field device. 1

Dieser erste Offline Parametrierschritt muss nicht zwingend an dem vorgesehenen Einsatzort des Feldgerätes 1 stattfinden, sondern kann bspw. auch an einem Ort außerhalb der Automatisierungsanlage stattfinden. Auf diese Weise lässt sich auf besonders einfache Weise die Parametrierung des Feldgerätes 1 durch einen Bediener durchführen.This first offline parameterization step does not necessarily have to take place at the intended place of use of the field device 1, but may, for example, also take place at a location outside the automation system. In this way, the parameterization of the field device 1 can be performed by an operator in a particularly simple manner.

Anschließend wird das vorparametrierte Feldgerät 1 an eine Zweidrahtleitung 7 der Automatisierungsanlage angebunden bzw. angeschlossen und somit auch vollständig, d.h. alle dem Feldgerät 1 zugehörigen Module 4, 5, 8, 9, 10, 12, 13 mit Energie gespeist.Subsequently, the pre-parameterized field device 1 is connected or connected to a two-wire line 7 of the automation system and thus also completely, i. all the field device 1 associated modules 4, 5, 8, 9, 10, 12, 13 fed with energy.

Die folgende Online Parametrierung sieht vor, dass das Feldgeräte 1 nach dem dieses an die Zweidrahtleitung 7 angebunden wurde, zumindest auf die im nicht-flüchtigen Speicher 5 hinterlegten Parameter zurückgreift, umso die Parametrierung aller dem Feldgerät 1 zugehörigen Module 4, 5, 8, 9, 10, 12, 13 durchzuführen. Denkbar an dieser Stelle ist auch, dass während der Online Parametrierung neben dem im nicht-flüchtigen Speicher 5 hinterlegten Parametern auch weitere Parameter über ein Bediengerät 2 dem Feldgerät 1 zu dessen Parametrierung zugeführt werden. Dies kann beispielsweise wiederum über das Funkmodul 4 des Feldgerätes 1 mittels eines entsprechend ausgebildeten Bediengerätes 2 durchgeführt werden, wobei in dem Fall das Funkmodul des Feldgerätes über die Zweidrahtleitung 7 und nicht mittels der Batterie 3 mit Energie versorgt wird.The following online parameterization provides that the field device 1 after this has been connected to the two-wire line 7, at least on the stored in the non-volatile memory 5 parameters, the parameterization of all the field device 1 associated modules 4, 5, 8, 9th , 10, 12, 13. It is also conceivable at this point that, in addition to the parameters stored in the non-volatile memory 5, further parameters are also supplied to the field device 1 for its parameterization via an operating device 2 during the online parameterization. This can in turn be carried out, for example, via the radio module 4 of the field device 1 by means of a correspondingly designed operating device 2, in which case the radio module of the field device is supplied with energy via the two-wire line 7 and not by means of the battery 3.
